To all 107mm t may concern.'

Be it known that I, JAMES E. Mimo, a citizen of the United States, residing at Palestine, in the county of Wirt and State of West Virginia, have invented new and useful Improvements in Depth-Gages for F illister or Rabbet Planes, of which the iollowing is a specilcation.

This invention relates to a depth gage for lllister or rabbet planes, the present application being a division of my prior application for adjustable lillister or rabbet planes,

Y filed March 28, 1918, Serial No. 225,151.

The object of the invention is to provide a convenient, reliable and eliicient type of gage for regulating the depth of cut, which gage may be adjusted to vary its working position for any depth of cut and quickly removed when it is desired to make abnormally deep cuts or work close to a marginal surface.

The invention consists in the features 0I construction, combination and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawing, in which Figure 1v is a view in side elevation, looking toward the right hand side of the plane, and showing my improved gage applied for use.

Fig. 2 is a vertical transverse section on line 2-2 of Fig. l.

Fig. 3 is a similar view with the depth gage removed.

Referring to the drawing, 1 designates the body or stock of the plane, including a bottom plate -or shoe 2 and a continuous side plate 3, said side plate being shown in the present instance at the right hand side of the stock. The bottom plate is divided, as is usual in planes of this character, to provide the throat 6, through which the cutting edge of the plane-iron or cutting-bit 7 projects.

A gage 67 is provided for limitingthe depth of the cut, and comprises a bar eX- tending longitudinally upon tlie outer side of the side plate 3 and adjustable to different elevations to vary the depth limit of the cut to any desired extent. As shown, the bar 67 is pivotally connected at its ends with the lower ends of a pair of swinging arms 68 having crank disks 69 at their upper ends, said crank disks being coupled by a connecting rod 70 holding the crank disks properly spaced. The arms 68 are made of Renewed April 15, 1920.

spring metal and have bowed lower ends, and the bar 67 is provided in alinement with said arms with studs 7l adapted for engagement with gage sockets or recesses 72 formed in the side plate 3. The sockets or recesses extend on arcs concentric with the pivot members of the arms and are arranged at diiierent elevations, so that by engagement ci the studs 71 under the spring action of the arm 68, with horizontally alined sockets disposed at a desired elevation the bar will be spaced a determined distance from the surface of the bottom plate to limit the depth of the cut to the desired degree. On the face of the side plate 8 is provided a suitable inch or other scale for indicating the degrees of adjustment to which the bar may be set, the divisions of which scale are in proper alinement with the sockets 72. The crank disks 69 of the arms 68 are formed with threaded openings which engage reduced threaded stems 73 upon the outer ends of rotary shafts 74, which stems thus support and hold the disks 69 pressed against the face of plate 3. The shafts 74 are journaled in bearings 75 on the plate 3 and are provided at their inner ends with actuating knobs or heads 76. At the intersection of the shaft 74 with the reduced stem 73 shoulders are formed against which bear washers or abutment disks 77 which are threaded on said stems and then punch- .keyed or otherwise locked in engagement with the threads, which abutments are movable in counterbores or recesses 78 formed in the bearings. A coiled spring 79 is interposed between each bearing and the knob or head 76 and normally acts upon and in coperation with the stem 73 to hold the crank disk 69 forced against the face of the plate 3, thus adapting the bowed free end of each arm 68 to have the desired spring locking action, while at the same time holding the gage members in close contact with the sides of the plate 3. It will be understood that by pulling outward on the arms 68 the studs 7l may be disengaged from the sockets they engage and the gage swung in one direction or the other to adjust the bar 67 to the desired elevation, and that as said bar swings downwardly it also swings forwardly, while on the upward movement of the bar it will also swing rearwardly, the construction being such that when the bar reaches the desired elevation the studs will snap into the sockets registering` therewith inwardly by the springs 79 so that the stems 73 and abutments 77 will be housed and concealed entirely within the recesses 78, thus leaving the outer face of the side plate 3 free from Vprojections so that it may slide freely in contact with the work or other object in certain operations of the tool. rl`he function of the rod 70 is to hold the disks 69 accurately spaced apart and kin proper relationship while the shafts 74 are being manipulated to connect the stems 73 with said disks. v

Having thus fully described my invention, l claim l. rlhe combination with a plane comprising a stock having a side plate, the said plate having arcuate series of sockets therein, of spring arms pivoted at their upper ends upon said plate and having their lower end bowed, forming spring members adapted to pass over said series of sockets, the said upper ends of the arms being provided with crank members, a gage bar carried by the bowed free ends of said arms, studs upon said gage bar adapted to interlock with said sockets, and a rod connecting the crank members of the said spring arms.

2. The combination with a plane having a stock provided with a side plate, of rock shafts mounted upon said plate, swinging arms having crank elements and connected with the rook shafts, said arms having bowed portions forming spring members, a gage bar pivotally connected with the bowed portions of the swinging arms, a casing between tlie crank elements of the swinging arms, interlocking means upon the bar andside plate adapted for engagement under pressure of the spring members of the swinging arms, and springs acting upon the rock shafts for normally holding the swinging arms under tension.

3. A, i'illister or rabbet plane comprising a stock having a side plate, rock shafts slidably and rotatably mounted upon said plate, swinging arms having crank elements detachably connected with the rock shafts, said arms having bowed portions forming spring members, a gage bar pivotally connected with the bowed portions of the Vswinging arms, a .connectionbetween the crank elements of the swinging arms, interlocking means uponthe bar and side plate adapted for engagement under the pressure of the spring members of the swinging arms, and springs acting upon the rock shafts for normally holding the swinging arms under tension and adapted upon the disengagement of said swinging arms from the rock shafts, to slide the shafts inwardly beyond the face of the side plate. Y

Il. ln a device of the class described, a piane comprising a stock having a side plate provided with spaced recesses, threaded stems rotatably mounted in said recesses, gage arms detachably connected to said stems at one end thereof, a gage bar connecting the said arms, a spring for each of said threaded stems tending to force the same inwardly from the outer surface of said side plate, and means for limiting the movemen of said stems. Y

In testimony whereof I affix my signature.
